( Granted under the act of March 3, 1883, as amended April 30, 1928; 370 O. G. 757) 3 Claims.

The invention described herein, if patented, may be manufactured and used by or for the Government for governmental purposes, without the payment to me of any royalty thereon.

The present invention relates to stoves, and

more particularly to a novel form of camp stove suitable for military troops, or as a part of civilian camping equipment.

The principal object of the present invention is the provision of an extremely simple, light, and compact stove structure including a stove body, together with front and rear panels which may be easily attached to, or detached from, the body of the stove, and which are provided with separable braces or legs to give stability to the stove structure.

A further object of the invention is the provision of a pair of stove panel units of such design and construction that they may be combined with one or two ordinary 5-gallon metal gasoline cans of conventional design, in order to provide a stove structure, the arrangement being such that the front and rear panels'are relatively flat and will occupy a minimum amount of space and so that a very satisfactory stove may be improvised by cutting the top' and bottom from a standard shape fuel can and assembling the panel units at either end of the can so that the can body will act as the fire chamber of the stove, while the front and rear stove panels will provide adequate means for attachment of flues and a satisfactory fuel door.

' A further object of the invention resides in the provision of a pair of front and rear panels adapted to be assembled at the opposite ends of a rectangular stove body, together with braces arranged to support the panels and to interlock the panels and the stove body.

Referring now more particularly to the drawing attached to and forming a part of the present specification:

Fig. 1 is a perspective view of an assembled stove constructed in accordance with the teachings of this disclosure;

Fig. 2 is a longitudinal sectional view through the stove illustrated in Fig. 1.

The body I I of the stove consists of a relatively long, square sheet metal tube which in the preferred construction is of dimensions approximating 9%; x 9%; x 24 and which may be made by ordinary '20-gauge black iron, seamed along one side as illustrated at l2. It may be pointed out at this point of the application, however, that while this stove body portion Il may be manufactured as a part of the assembly, yet it is one of the main features of the present invention that the front and rear panels to be hereinafter described may be attached to any conventional type of square gasoline can; and, since such containers or gasoline cans are in wide use at the present time and easy to obtain in any locality, a set of panels may be sold as an article of commerce to be used in connection with a stove body portion obtained elsewhere. In this connection it may be pointed out that it has been common practice in some localities for many years to improvise stoves from fuel oil containers, usually rom two 5-gallon gasoline tins telescoped into each other. Such improvised structures have been satisfactory within reasonable limits, but the present invention proposes to provide end panels so arranged that they may be easily attached'to the opposite ends of a conventional type of fuel can and permanently secured theretoto provide a more neat, efficient and rugged stove, and to provide mechanically perfect flue mountings'and fuel doors, and thus overcome the deficiencies of the so-called Yukon stoves heretofore known.

To'this' end the present invention provides a substantially square front panel l3 having deep side flanges l 4, top flanges l5, and bottom flanges Hi. The panel is provided with a hinged door I! preferably mounted on hinges as illustrated at l8 and closedby a latch I9. The door ll may also be provided with any desired type of draft control device, such as the pivoted door 2 I, arranged to close'the draft door opening 22 in the door H.

The upper flange l5 and lower flange l6 of the end'panel'are perforated at 23 and 24, respectively, to receive the opposite ends of a pair of stove legs or braces. Each of these includes a vertical riser portion 25, the lower end of which is joined to the stove panel by a horizontal rail portion 26 terminating in a vertical pin 27, which enters one ofthe lower openings 24 in the bottom flange l6 and extends upwardly through a registering opening 28 in the body II of the stove. The upper end of the riser portion 26 of each of :the'jlegs extends inwardly to provide a top rail 3| terminating in a downwardly extending'pin 32 passing through the' opening 23 in the top flange of the stove panel and through an opening 33 in 'tliebody portion ll of the stove. The top rail 3i 'oftli'e stove leg is formed to include a limiting 'stop 34 spaced apart from the pin 32 sufliciently so that it will bear against one of the side flanges M of the stove panel and prevent pivotal movement of the leg 25 about the pins 21 and 32.

From the foregoing it will be seen that the panel may be secured to the stove by simply positioning the flanges l4 over the ends of the stove body I I, or by inserting the lower pin 21 through the registering openings 24 and 28, and then flexing the leg portions sufliciently to snap the upper pins 2! into position through the registering openings 23 and 33.

The panel may be similarly secured to a gasoline can by simply positioning the flanges [4 over the open end of the can, perforating the can by the use of any sharp instrument inserted through the openings 23 and 24, and locking the panel in position on the end of the gasoline container by inserting the lower pins 21, and snapping upper pins 27 into position through the openings 23 and 24 in the same manner as just described.

The rear panel |3a is of square shape, of the same dimensions as the front panel l3, and includes side flanges Ma, as well as a top flange Ia and bottom flange I6a, corresponding to and matching the flanges l4, I5, and I6 of the front panel. Similarly, it is. provided with a pair of resilient rectangular wire legs 25a, having lower rails 26a terminating in lower pins 21a, and top rails 3la terminating in top pins 32a, together with stop portions 34a which function in a manner identical to the stop portions 34.

The upwardly extending bottom pins 21a and downwardly extending top pins 32a pass through the. openings. 214a and 23a in the bottom flange I642: and top flange l5a of the rear panel I30. and through openings 28a and 33a in the body portion I i, to lock the stove panels and body together in. the same manner as described, in connection with the front panel.

The rear panel l3a is provided with a flanged flue opening 38 to establish communication between the fire chamber of the stove and a flue pipe 31 extending to the stack 36. As hereinbefore pointed out, the present invention provides a novel and useful collapsible stove structure that may be assembled simply by placing the opposite end panels 13 and I311 on the opposite ends of the body H and locking the entire assembly together by snapping the legs 25 and 25a into position so that the upper and lower pins of theselegs pass through the registering openings in the stove body and. panel flanges, and thus secure the entire stove in assembled position. Further, the panels l3 and |3a may be utilized without the body portion II to provide efficient flue mounting means and fuel door mechanism, and thus permit one or two ordinary square sheet metal gasoline containers to be improvised as a heating or cooking stove. This may be done merely by cutting out the ends of the gasoline container, perforating the sheet metal of the container, and locking the stove in assembled position.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a stove structure, in combination, a body portion comprising a relatively long, narrow rectangular sheet metal tube including perforations in its top and bottom walls adjacent each end of each of said walls; a, pair of end panels for said stove body; each of said panels including a substantially square, flat plate having relatively deep flanges on the top, bottom, and both sides: the top and bottom flanges of each plate including perforations adjacent the opposite side flanges thereof; stove legs attached to the opposite sides of each of said panels; each of said stove legs comprising a vertical riser portion spaced apart from the panel, top and bottom rails extending horizontally from the top and bottom of said riser to the top and bottom flanges of the panels respectively; said rails terminating in a downwardly extending top pin and an upwardly extending bottom pin respectively; said top and bottom pins adapted to extend through the perforations in the panels and through the aforementioned perforations in the body of the stove to secure the panels in position on said stove body, together with limiting stops for said legs, each stop consisting of a vertical projection on one of the aforementioned rails at a point adjacent one of said pins; the limiting stops, contacting the flange of the end panel to prevent pivotal movement of the legs.
